And splitting the qt5 recipes (e.g. to > have only qtbase, qtdeclarative in oe-core and "additional" modules in > separate meta-qt5) isn't very good, because they are quite tightly > coupled (so upgrading recipes in meta-qt5 would be in many cases > incomatible with qtbase version in oe-core and vice-versa).
What dependencies on other layers does meta-qt5 have? If the policy is all qt5 things into meta-qt5, the risk is a fairly large set of layer dependencies for meta-qt5. There is some perception I don't like external layers which isn't true. What I do dislike is "dependency creep". If the meta-qt5 isn't usable without pulling in chunks of meta-oe for example, I'd think that rather sad and it might as well move to meta-oe at that point. Also, whilst there are only 6 qt4 recipes in core, they are (at least as far as I know) the core qt components that people base off so in that sense we're enabling developers and don't have a ton of "apps" around they probably wouldn't want to use.
